Why is Sodium kept immersed in Kerosene Oil?

Sodium is the metal stored in kerosene oil in order to prevent it from coming in contact with oxygen and moisture.

Explanation

Sodium is a highly reactive metal and reacts vigorously with the oxygen, carbon dioxide and moisture present in the air such that it may even cause a fire. To prevent this explosive reaction, Sodium is kept immersed in kerosene because Sodium doesn’t react with kerosene.
